This Letter presents a search for new resonances decaying to final states with a vector boson produced in association with a high transverse momentum photon, V? , with V=W(?l?)V=W(?l?) or Z(?l+l-)Z(?l+l-), where l=el=e or µ. The measurements use 20.3 fb-1 of proton–proton collision data at a center-of-mass energy of View the MathML sources=8 TeV recorded with the ATLAS detector. No deviations from the Standard Model expectations are found, and production cross section limits are set at 95% confidence level. Masses of the hypothetical aTaT and ?T?T states of a benchmark Low Scale Technicolor model are excluded in the ranges [275,960] GeV[275,960] GeV and [200,700]?[750,890] GeV[200,700]?[750,890] GeV, respectively. Limits at 95% confidence level on the production cross section of a singlet scalar resonance decaying to Z? final states have also been obtained for masses below 1180 GeV.
